The data are of a simulated land only surface temperature difference between the middle Miocene at 15 million years ago and present day with US NCAR climate models. The data includes all available monthly sea surface temperature measurements from 1900 to 2000. The results recreate the temperature of 15 million years, ago which correlates to similar predictions for future climate warming. The areas of significant temperature increase (over 6 deg C) shown are in northern America and Europe. In Western and Southern Australia, Miocene temperature was 6 C higher than present, and likely due to a stronger Leeuwin Current carrying a greater amount of equatorial water from the tropics since the Indonesian sea straits were wider and the Indonesian throughflow could be stronger. The middle Miocene Climate Optimum at 15 ma is the most recent warming event in geological history. The results suggest that our planet is heading back to the middle Miocene climate but with a different mechanism.
